JOSEPH GAYNOR, OF NEW YORK, N. Y.

EXTENSIBLE CABINET.

T 0 all whom it may concern:

Be it known that I, JOSEPH GAYNOR, a citizen of the United States,residing at New York city, Brooklyn, county of Kings, State of New York,have invented new and useful Improvements in Extensible Cabinets, ofwhich the following is a specification.

This invention relates to an extensible cabinet of novel construction,provided with iiexible sides, so that its depth may be readily increasedor diminished. Means are provided for collapsing the sides to any extentdesired, and to lock them against further expansion or contraction afterbeing adjusted. y

The cabinet may be used as a wardrobe, a press, a box or for similarpurposes.

In the accompanying drawing: Figure 1 is a perspective View of myimproved extensible cabinet; Fig. 2 a vertical longitudinal sectionthereof, and Fig. 3 a detail of the locking means.

The cabinet comprises essentially a rigid back 10, a rigid front 11,carrying the door 12, and foldable sides 13 connecting the back with thefront. Sides 13 are composed of a flexible accordion plaited materialwhich permits them to be readily expanded or contracted. Centeredbetween back 1() and front 11, there is an oblong frame 14, to which theaccordion plaiting is attached at or about its center. This frame iscomposed of hollow and slotted side rails, and if desired of a similartop rail, while the bottom rail may be solid. Frame 14: is arranged inparallelism with back 10 and front 11, and corresponds in height andwidth to the height and width of said back and front. To both sides ofback 10 and front 11, there are pivoted near the corners thereof, arms15, as at 16. The two opposed arms 15 of each set are apertured at theiroverlapping inner ends for the reception of a common screw bolt 17engaging slot 18 of frame 14: and carrying winged nut 19. In order toadmit bolts 17 into slots 1S, the face of frame 14 remains uncovered. Tothis effect, the foldable sides 13 are formed of a front section and ofa rear section, the inner ends of which are respectively attached to thefront and back of the frame. rIhe heads 20 of bolts 17 are squared andare received within the hollow rails, so that they hold the boltsagainst rotation. If desired, arms 15 may also be pivoted to the top ofback 10 and front 11, the bolts carried by Specification of LettersPatent.

said arms engaging the top rail of frame 111. But these upper arms, whenemployed, should be slotted at their inner ends as at 21, so that theymay freely overlap.

`When the size of the cabinet is to be re duced, nuts 19 are slackenedand arms 15 are moved inward with their free ends, until the sides ofthe cabinet have been folded to the extent desired. The mits are thentightened up to lock the cabinet in its newly assumed position. Areverse operation will cause the size of the cabinet to be increased, aswill be readily understood.

The interior of the cabinet may bc adapted for the particular' use towhich the cabinet is to be put. Thus, if it is to be used as a wardrobe,hooks 22 may be secured to its back 10 and also to the top rail of frame14, as shown. But it is obvious that the interior fitting of the cabinetmay be differently arranged if desired.

claim:

1. An extensible cabinet comprising a front, a back, flexible top,bottom and side members connecting the front and back, a frameintermediate the front and back and having connection with said top,bottom and side members, upper and lower sets of side arms pivoted tothe front and back, means pivotally connecting the inner ends of thearms of each set to the sides of said intermediate frame, sets of armsconnecting the front and back at their upper edges, the inner ends ofthe arms of each set being slotted, and means operating through theslotted ends of said arms and having connection with the top of theintermediate frame whereby the front and back have adjustment toward andaway from each other.

2. An extensible cabinet comprising a front, a back, flexible top, sideand bottom members connecting the front and back, a frame intermediatethe front and back and having connection with said flexible members, apair of arms pivoted to the back at the upper edge thereof, a pair ofarms pivoted to the front at its upper edge, each arm having' a slot,and means operating through the slots on opposite arms of each pair andhaving connection with the top of said intermediate frame whereby thefront and back may be adjusted toward and away from each other.

3. An extensible cabinet comprising a front, a back, fiexible top,bottom and side members connecting the front and top, a

frame intermediate the front and back and having connection with saidlexible members, a pair of arms pivoted to the back at the upper edgethereof, a pair of arms pivoted to the front at its upper edge, each armhaving a. slot, opposite arms of each pair overlapping each other, meanspassed through the slots of the overlapping arms and having connectionwith the upper edge of said intermediate frame, a pair ot arms pivotallyconnected to each side edge of the back, a pair of arms pivotallyconnected to each side edge of the front, the arms that are pivotallyconnectedto the sides of the front and back having their inner endsoverlapping, and means connected to the overlapping parts of said armsand having connection with the sides of said intermediate frame wherebythe front and .back may be adjusted toward and away from each other.

It. An extensible cabinet comprising a front, a back, flexible top,bottom and side members connecting the front and back, a frameintermediate the front and back and having connection with said flexiblemembers, slotted arms pivotally secured to the upper edge of the back,slotted arms pivotally connected to the upper edge of the Jfront andoverlapping the first mentioned arms, means passed through theoverlapping portions of said arms and having connection with the top ofsaid intermediate frame whereby the front and back may be adjustedtoward and away from each other, a pair of arms pivotally secured toeach side edge of the back, a pair of arms pivotally secured to eachside edge of the front and overlapping the arms that are pivoted to thesides of the back, and means passed through the overlapping portions ofthe last mentioned arms and having connection with the sides of theintermediate frame to permit of adjustment of the front and back towardand away from each other.

5. An extensible cabinet comprising a front, a back, flexible top,bottom and side members connecting the front and back, a frameintermediate the front and back, the members which form the frame beinghollow and slotted, arms pivoted to the front and back, bolts carried bysaid arms and having squared heads that are movable within the hollowmembers which form the frame, the bodies of the bolts projecting throughthe slots of the members which Jform the frame, and nuts for clampingthe bolts to the arms whereby the front and back may be adjusted towardand away from each other.

6.
